Cholesteatoma

Cholesteatoma (pronunciation: /ˌkɒlɪstiːəˈtoʊmə/) is a non-cancerous growth that can develop in the middle ear behind the eardrum. This condition can be a birth defect (congenital), but it more commonly occurs as a complication of chronic ear infection.

Etymology

The term "Cholesteatoma" is derived from the Greek words "chole" meaning bile, "steat" meaning fat, and "oma" meaning tumor. Despite its name, a cholesteatoma is not a tumor and does not contain either bile or fat. It was named by the German pathologist Johannes Müller in 1838, who mistakenly believed the cysts to be filled with cholesterol crystals.

Symptoms

The symptoms of a cholesteatoma can vary, but common signs include:

Treatment

Treatment for cholesteatoma usually involves surgery to remove the growth. In some cases, long-term follow-up care may be needed to prevent recurrence.
